Subsequent pathnames will -use the Acorn format: The full-stop or period character is a pathname -delimeter, and the slash character is not interpreted; the reverse position -from Unix. Thus "libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c". - -This support was contributed by Peter Greenham. -(peterg@angmulti.demon.co.uk). - -Installing LibTIFF: - -LIBTIFF uses several files which have names longer than the normal RISC OS -maximum of ten characters. This complicates matters. Maybe one day Acorn will -address the problem and implement long filenames properly. Until then this -gets messy, especially as I'm trying to do this with obeyfiles and not have -to include binaries in this distribution. - -First of all, ensure you have Truncate configured on (type *Configure -Truncate On) Although it is, of course, preferable to have long filenames, -LIBTIFF can be installed with short filenames, and it will compile and link -without problems. However, getting it there is more problematic. -contrib.acorn.install is an installation obeyfile which will create a normal -Acorn-style library from the source (ie: with c, h and o folders etc.), but -needs the distribution library to have been unpacked into a location which is -capable of supporting long filenames, even if only temporarily. - -My recommendation, until Acorn address this problem properly, is to use Jason -Tribbeck's LongFilenames , or any other working system that gives you long -filenames, like a nearby NFS server for instance. - -If you are using Longfilenames, even if only temporarily to install LIBTIFF, -unpack the TAR into a RAMDisc which has been longfilenamed (ie: *addlongfs -ram) and then install from there to the hard disk. Unfortunately -Longfilenames seems a bit unhappy about copying a bunch of long-named files -across the same filing system, but is happy going between systems. You'll -need to create a ramdisk of about 2Mb. - -Now you can run the installation script I've supplied (in contrib.acorn), -which will automate the process of installing LIBTIFF as an Acorn-style -library. The syntax is as follows: - -install <source_dir> <dest_dir> - -Install will then create <dest_dir> and put the library in there. For -example, having used LongFilenames on the RAMDisk and unpacked the library -into there, you can then type: - -Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$ ADFS::4.$.LIBTIFF - -It doesn't matter if the destination location can cope with long filenames or -not. The filenames will be truncated if necessary (*Configure Truncate On if -you get errors) and all will be well. - -Compiling LibTIFF: - -Once the LibTIFF folder has been created and the files put inside, making the -library should be just a matter of running 'SetVars' to set the appropriate -system variables, then running 'Makefile'. - -OSLib - -OSLib is a comprehensive API for RISC OS machines, written by Jonathan -Coxhead of Acorn Computers (although OSLib is not an official Acorn product). -Using the OSLib SWI veneers produces code which is more compact and more -efficient than code written using _kernel_swi or _swi. The Acorn port of -LibTIFF can take advantage of this if present. Edit the Makefile and go to -the Static dependencies section. The first entry is: - -# Static dependencies: -@.o.tif_acorn: @.c.tif_acorn - cc $(ccflags) -o @.o.tif_acorn @.c.tif_acorn -Change the cc line to: - - cc $(ccflags) -DINCLUDE_OSLIB -o @.o.tif_acorn @.c.tif_acorn - -Remember, however, that OSLib is only recommended for efficiency's sake. It -is not required. |
